public class Index {

    @RequestMapping(value = "/customer", method = RequestMethod.GET)
    public Customer getIndex() {
        System.out.println("executing in index controller");
        Customer customer = new Customer("Mike", "John", "mike.john@gmail.com");

        return customer;

在控制器中，尝试更改

属性，这样就找不到

path=“/customer”

@wdc path，当我尝试更改它时会出现错误。据我所知，您已使用“/”作为应用程序的根，而我没有看到任何名为“/customer crm”的路径。因此，对我来说，您想要的页面似乎在“localhost:8080/api/customer”下可用。“customer-crm”是应用程序上下文，我也尝试了“localhost:8080/api/customer”，但不起作用。在controller中，尝试更改
